Over the past decade, atomically thin two-dimensional (2D) materials have made their way to the forefront of several research areas including batteries, (electro-)catalysis, electronics, and photonics[1]}, [2]}. This development was prompted by the intriguing and easily tunable properties of atomically thin crystals and has been fueled by the constant discovery of new 2D materials and the emergent concepts of lateral[3]} and vertical[4]} 2D heterostructures, which opens completely new possibilities for designing materials with tailored and superior properties.
